随着分子生物学研究的进展,分子靶向治疗已成为除手术、放疗、化疗之外的第4种治疗方法,越来越多的用于临床治疗恶性肿瘤。分子靶向药物进入体内能够特异地选择致癌位点,杀伤肿瘤细胞,而不会波及周围正常的组织细胞,因此分子靶向治疗又被称为\"生物导弹\"。与传统化疗药物相比,分子靶向药物具有特异性强、疗效明显、副作用少等优点。按照分子靶向药物的性质主要归为两大类:一类是单克隆抗体,如西妥昔单抗等;另一类是单靶点或多靶点的小分子抑制剂,如吉非替尼等。表皮生长因子受体(EGFR)对肿瘤的生长、发展以及肿瘤干细胞的维持都有着非常重要的作用,并且在多种实体瘤中存在过表达或异常表达,因此在肿瘤治疗中,EGFR成为一个非常重要的用药靶点。现主要对目前国内已上市的针对EGFR的分子靶向药物最新的临床研究进展作一简要综述。 相似文献

Eight monoclonal antibodies (McAbs), directed against antigens on rat cauda epididymal spermatozoa, were tested for their capacity to interfere with fertilization in vitro as a means of identifying molecules with a potential role in sperm-egg recognition and fusion. Antigens recognized by the McAbs were visualized on live spermatozoa by indirect immunofluorescence (IIF) and characterized by immunoblotting. Five McAbs (designated 1B5, 2C4, 4B5, 5B1, and 8C4) recognized antigens specifically on the sperm acrosome and three (designated 2B1, 2D6, and 6B2) bound to the flagellum. Of the eight McAbs investigated, three (2B1, 2C4, and 6B2) were effective in blocking fertilization in vitro when added as culture supernatants to mixtures of sperm and eggs. McAb 6B2 was inhibitory due to its ability to agglutinate spermatozoa. McAbs 2B1 and 2C4 did not agglutinate capacitated spermatozoa, had no observable effect on motility, and yet blocked fertilization in a dose-dependent manner. McAb 2C4 did not give a reaction on immunoblots, but the 2B1 antigen was identified as an Mr 40 kD glycoprotein. McAb 2B1 appeared to block fertilization at the level of zona binding, whereas the effects of 2C4 were directed more against zona penetration and/or fusion with the vitellus. When sperm-egg complexes were stained with 2C4 or 2B1 McAbs and viewed by IIF, all spermatozoa that were attached to the zona showed fluorescence on the head. These results suggest that different antigens on the rat sperm head participate in different aspects of the fertilization process and that during capacitation there is either exposure of these antigens or else they migrate to their site of action from the flagellum. 相似文献

Trypanosomes possess a single flagellum that is attached to their cell body via the flagellum attachment zone (FAZ). The FAZ is composed of two structures: a cytoplasmic filament complex and four microtubules situated next to it. There is a complex transmembrane crosslinking of this FAZ to the paraflagellar rod (PFR) and axoneme within the flagellum. We have partially purified the FAZ complex and have produced monoclonal antibodies both against the FAZ and the paraflagellar rod. The two antibodies against the FAZ (L3B2 and L6B3) recognise the cytoplasmic filament in immunofluorescence and in immunoelectron microscopy. On western blot, they detect a doublet of high molecular weight (M(r) 200,000). Two anti-PFR antibodies (L13D6 and L8C4) recognise the paraflagellar rod in immunofluorescence, but show a difference on Western blot: L13D6 recognises both major PFR proteins, whereas L8C4 is specific for only one of them. Using these new antibodies we have shown that although the growth of both cytoplasmic FAZ filament and external PFR are related, their growth initiates at different time points during the cell cycle and the two structures elongate at distinct rates. 相似文献

Combinatorial treatments including vaccines,chemotherapy and monoclonal antibodies for cancer therapy 总被引:1,自引:0,他引:1
Accumulating evidence suggests that despite the potency of cytotoxic anticancer agents, and the great specificity that can
be achieved with immunotherapy, neither of these two types of treatment by itself has been sufficient to eradicate the disease.
Still, the combination of these two different modalities holds enormous potential for eliciting therapeutic results. Indeed,
certain chemotherapeutic agents have shown immunomodulatory activities, and several combined approaches have already been
attempted. For instance, chemotherapy has been proven to enhance the efficacy of tumor cell vaccines, and to favor the activity
of adoptively transferred tumor-specific T cells. A number of mechanisms have been proposed for the chemotherapy-triggered
enhancement of immunotherapy response. Thus, chemotherapy may favor tumor cell death, and by that enhance tumor-antigen cross-presentation
in vivo. Drug-induced myelosuppression may induce the production of cytokines favoring homeostatic proliferation, and/or ablate
immunosuppression mechanisms. Furthermore, the recently reported synergy between monoclonal antibodies and chemotherapy or
peptide vaccination is based upon the induction of endogenous humoral and cellular immune responses. This would suggest that
monoclonal antibodies may not only provide passive immunotherapy but can also promote tumor-specific active immunity. This
article will review several strategies in which immunotherapy can be exploited in preclinical and clinical studies in combination
with other agents and therapeutic modalities that are quite unique when compared with “conventional” combination therapies
(ie, treatments with chemotherapeutic drugs or chemotherapy and radiotherapy based protocols). The results from these studies
may have significant implications for the development of new protocols based on combinatorial treatments including vaccines,
chemotherapy and monoclonal antibodies, suggesting an exciting potential for therapeutic synergy with general applicability
to various cancer types. Given the complicity of immune-based therapies and cancer pharmacology, it will be necessary to bring
together cancer immunologists and clinicians, so as to provide a robust stimulus for realizing the successful management of
cancer in the near future. 相似文献
